Application filed April 9, 1919., Serial No. 238,736.

To @ZZ whom t may concern: 4,

Be it known that l, Tnnononn BAYMoND CAMERON, a citizen of the UnitedStates, residing at San Antonio, in the county olE Bexar and `State ofTexas, certain new and useful :improvements Ain Mechanical Packers, ofwhich the following is a speciiication. v

My invention relates to mechanical packing apparatus, adapted to use inconnection with a power operated press, such as a cotton press, whilenot necessarily restricted to this use.v I, y Y

An important object "of the invention is to provide automatic means tocause the platen oi the packer tol reciprocate contiim-l ously duringthe operation o'j'the apparatus, such means embodying a flexible elementand a worm drum upon which the flexible element is wound. A l Otherobjects and advantages oit the invention will be apparentduringthecourse ofthe following description l ln the accompanyingdrawings, lforming' a part ci this specification and `in which likenumerals are employedV to V designate 'like parts-throughout thesame, p1

ln the drawings, whereinior' lthe lpurpose ofillustration is `shown a`preterred embodi- Ainvention, `a supportingy frame is shown comprisinglongitnc inal beams ,10, connected by transverse-beams 1l, and l2. heouter ends oi the-beamed@ are supporttheirV inner ends are connectedwith a block 14, secured `to the head platen 15` oilthefpower press.

Secured tol theirearbearn 10 are vertical beams 16,`to which isconnecteda guard 17, asshown.` y

have invented into a recess 27 and passing a transverse pin 28 throughthe Rigidly secured to the transverse beams l2, as shown in Fig. 1, arevertical guide sleeves 18, receiving ram-posts 19, adapted to.,reciprocate therein.` At their upper ends, these ram-posts are connectedwith sockets or couplings 20, rigidly secured to a head-yoke 21. Attheir lower ends, the rain-posts 19 are ksecured to couplings 22,rigidly lsecured to a platen 23, as shown. rihrs platen is adapted tooperate with a press box 24.

1 Connected with ,the transverse beams 11 and 12 are bearings 24,rotatably receiving a horizontal shaft 25. This shaft has two worm drums26, rigidly secured thereto. '.lhesc worm drums have flexible elements,

, such as cables 27, wound thereon. The cable `is anchored to each wormdrum bydepressing portiomas shown in Figs. (3 and T,

formed in the worm drum,

drum, outwardly o1c the depressed portion of the cable.

The lower ends of the cables are secured .to attaching elements 29,pivoted to the ends oi a horizontal equalizing bar 30, having anapertured head 31,., formed between theends thereof to loosely receive apin 32, carried by the platen,l The head 31 is arranged beneath andcontacts with a compressible coil spring 233, contacting with the nut34, carried by the pin 32. The function oi" the bar-30 is to maintainthe cables 2T saine tension. The upper ends of thccables are connectedwith eye -bolts 35, operatingn througlr openings in the head-yoke 2l.These eye-bolts have their upper ends screwthreaded and engaged byadjusting nuts 36, as shown. .it is` thus seen that rotation of theworin drums-will effect the longitudinal movement of the cables 2T whichin turn will cause the platen 23 and associated elements to bereciprocated.

' The shaft 25 receives its rotation from a large gear 37,di'iven by asmall gear 38, rigidly secured 'to a counter-shaft 39, journaled throughstationary bearings'40,` rigidly secured to the transverse beams 12.

The numerals-1 designates a tight pulley rigidly secured to thecounter-shaft 39, and 42 and 43 are loose pulleysrotatable thereon. Thenumeral 44 designates an open belt, and

at the ,through bearings 5l.

Y mounted upon posed near the 23, as shown.

45 a crossed belt, these belts'engaging-a common driving pulley, notshown. Y

Means are provided to shift these belts 44 and 45, comprising shiftingarms 46,`having heads 47 to suitably receiveth'e belts therein. Thesearms are rigidly secured to a horizontal reciprocatory erating instationary guides 49.

Arranged transversely-of the; platenV 23 is a' horizontal rock-shaft 50,journaled This rock-shaft has an upstanding crank 52 (see Fig. 4)rigidly Asecured thereto, having pivotal connection with a link 53,pivoted to one side of the sliding fra-me'48. A lever 54 the rock shaft50, and discrank 52. This lever carries a loop 55, extending uponopposite sides thereof, and loosely receiving the upper end of the crank52. In operation, whenthe shaft 50 is turned, the crank 52 willmove thelever 54 past dead center, the lever then automatically swinging to theextreme position upon one side of dead crank 52, the crank then engagingthe end of the loopV 55. This movement ofthe lever 54 'is-effected by aweight 56,'rlg1dly securedV a to the same near its free end. 30,

A tappet Varm 5 7 is also rigidly `secured to 60, secured to thehead-yoke 2l andplaten kA manually operated crank 6l is rigidly Ysecuredto Vone end of the rock shaft 50 and v25 willrcause the Ywormthis crank is adapted to be held within a forked latch 62, rigidlysecured to a rockshaft 63, journaled through bearings 64. This rockshaft is turned by a crank 65. T1fl/'hen the rock-shaft 50 is turned bymeans of the crank 6l so thatpit assumes the intermediate position, the,belts 44 and 45 will .be shifted to the loose pulleys 42 and 43,

whereby the machine will be stopped, the

latch 62. Y l Y The operation of the apparatus is as follows: v

With the belts inthe position shown Vin Fig. l, the open belt 44 may beassumed to be driving the fast pulley 41, in the direction crank 61being then held within the forkedV of lts arrow. As viewed in F ig. 3the shaft v 25 will,V then be rotatedI counter-clockwise.y Thiscounter-clockwise rotation of the shaft drums 26 to rotate inthe samedirection, whereby the platen 23 will be elevated.

When the crank 52 moves forwardly suficiently, thepopenbelt V44 is shifted to the loose pulley 42, while the crossedjbelt 45will engagethe fast pulley 41. It is thus seenthat the rotation of theshaft 25 will be reversed, andthev platen will move downwardly until thetappet 59 engages the tappet arm 57, to turn the rock-shaft 50 in anopposite direction. When this rock shaft 'i the belts are again fastpulley and the crossed belt the inner loose Vpulley 43, the platenVagain rising. This operation is continued automatically until both beltsare shifted upon the loose pulleys, which' is accomplished by swingingintermediate position.
